FEED CUTTER.

SPECIFICATION ionizing part of Letters Patent No. 378,112, datedFebruary 21, 1888.

Application filed December 27,1886. Serial No, (No model.)

To aZZ whom it mcty concern.-

Be it known that I, Ennnnznn \V. RIDER, ofltacinc, in the county ofRacine, and in the State of \Visconsin, have invented certain new anduseful lm p rovcnients in Feed-Gutters and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to feedcutters; and it consists incertainpeculiarities of construction and combination of parts, to behereinafter de scribed with reference to the accompanying drawings andsubsequently claimed.

In the drawings, Figure 1 represents a front elevation of my invention;Fig. 2, a side elevation; Fig. 3, a similar view with the driving-gearremoved, and Fig. 4 a detail view of a pawland-ratchet mechanism foractuating the feed-rolls.

Referring by letter to the drawings, A represents the feed-box of mymachine, mounted in a suitable frame, said box being provided at itsfront end with a shear-plate, B, and secured to the frame adjacent tothis plate is a knife-guard, O. J'ournaled in suitable bearings so as tooperate within the box A are feedrolls D D, of the ordinary constructionand adjustment. Fast on the journals (4 a of the feed-rolls D D, at thedrive side of the machine, are ratchetwheels E E", and loose on thesejournals are arms F F, the latter having pivotally connected theretopivoted springactuated pawls G G, that engage said ratchetwheels.

In Fig. 4 l have shown a detail view of the pawland-ratchet mechanism,and in this instance I employ a spring, I), to keep the pawl G inengagement with the arm F.

If found desirable,the pawl G may be weighted, as shown at 0, Figs. 2and 3.

To the arms F F, I pivotally connect the forward ends of links H it,that have their rear ends similarly connected to the vertical ears dol'a rack-plate, l, the latter being operativclyarranged in guides c,suitably secured to the box A.

Theforward end of the rackplatel is turned out at right angles to forman ear, f, and this car has a perforation that serves as a guide for arod, J, connected with a crank-arm, K, on the inner end of a shortshaft, K, operativein a. suitable bearing, 9, secured to an extension ofa transverse brace, L, that is in turn fastened to the under side of thebox A, said short shaft being provided with a bevel-pinion, M, keyedthereto at its outer end. The rod J is provided with a collar, h, andbetween this collar and the earf of the rack-plate I is arranged aspiral spring, N, the tension of the latter being regulated by athumbnut, i, on the forward end of said rod.

Pivotally connected to the adjacent side of the box A is a dog, 0, thatserves to engage the rack-plate I at such times as it may be desirableto stop the feed of the rolls D D.

In order to vary the feed of the rolls D D, the crank-arm K is providedwith a series of perforations, j, and the throw of the rod J isconsequently lengthened or shortened, accord ing to its engagement withsaid perforations.

Meshing with the bevel-pinion M is a similar pinion, 1?, on the adjacentend ofa crankshaft, Q, that has its bearing is It, respectively, securedto the extension of the "eross'brace L and a standard, L, at the frontof the frame. To the crank-portion Qoftheshaft Q is loosely connectedone end of a knife, R, that comes across the month of the feed'box A,the opposite end of this knife being also loosely connected to a stud,m, on the lower terminus of a curved lever-arm, S, pivotally secured toa bracket, T, the latter being secured to a front standard, T, of thesupporting'fraine and projected over to nearly or quite the transversecenter of said box.

The crank-shaft Q has keyed thereto a flywheel, U, and by a suitableconstruction and arrangement of gearing any desired speed may be givensaid shaft. In this instance I show a bevel-pinion, V, fast on the shaftQ and arranged to mesh with a bevel gear-wheel, V, journaled in abearing, X, secured to the extension of the cross-brace L, said wheelbeing twice the diameter of the intermeshing pinion and having a crank,Y, fast on itsjournal. If found desirable, the speed-gear may be omittedand the crank Y applied to the flywheel U.

A. springarm, Z, has one end thereof rigidly secured to the under sideof the brace-piece L and its other end brought over upon a transversebar, Z, to which latter are adjustably" shown by Fig. 1 when thecrank-shaft Q. is operated this knife will be drawn thereby toward theoperator, while at the same time the levervarm S operates to drive saidknife in the same direction, whereby a double power is exerted toproduce an easy, sliding, and shear cut in a direction away from saidoperator. While the machine is running that end of the knife R nearestthe operator describes a circle, 0, as shown by dotted lines, Fig. 1,the other end of said knife traveling on an are, p, of a circle having alarger diameter than the one 0, and also illustrated by dotted lines inthe same figure. The knife It begins to out at that side of the boxnearest the operator and gradually performs its function as the oppositeside of this box is approached, the inclination of this i knife beingdiminished as the work proceeds until at the time its edge has entirelypassed the shear-piate B said knife will be nearly or quite horizontal.

In Fig. 1 is shown by dotted lines the knife in various stages of itsdescent, and by this illustration it will be noticed that said knifedoes not come at'any one time on. the whole mass that may protrude fromthe mouth of the feed-look. The pinion M, meshing with the pinion I? onthe crankshaftfimparts motion to the crank-arm K, and this latter partin turn imparts motion to the rod J, that has a loose bearing in the earf of the rack-plate I. When the dog 0 is clear of the rack-plate I, thelatter is actuated by the rod J, and, being linked to the arms F F,causes the pawland-ratchet mechanism,previously described, to partiallyrotate the feed-rolls D D when the knife R is on. its return aftercompleting acut, thereby bringing more material from the box A into thepath of said knife, the length of feed being regulated by the throw ofthe rod above described.

YVhen it is'desirable to stop the revolution of the feed-rolls, the dog0 is dropped, and the raolr-plate I is thereby held stationary, the rodJ having its play through the perforation in the earf of said plate.

plate, a pinion having its journal provided with a crank-arm, a roduniting the loose plate with the crank-arm, and a drive'shaft having apinion arranged to mesh with the one above specified, substantially asand for the purpose set forth.

2. In a feed-cutter, the combination of a box mounted in a frame,feed-rolls operatively arranged in the box and having their journals atone end provided with ratchet-wheels, arms loosely arranged on saidjournals and carrying pawls to engage the ratchet wheels, a looserack-plate operatively connected to the adjacent side of said box andunited by links with the pawl-arms, a pivoted dog arranged to be broughtinto engagement with the rack-plate, a pinion having its journalprovided with a ciankarm, a rod having a loose bearing in an ear of saidrack-plate and connected with the crank-arm, a spring arranged on therod, and a drive-shafthavinga pinion arranged to mesh with the one abovespecified, substantially as and for the purpose set forth.

3. In a feedoutter, the combination of a suitable frame, a box mountedin the frame,.

feed-rolls arranged in the box, a transverse knife, a crank-shaftloosely connected to one end of the knife, a leverarm likewise connectedto the other end of said knife, ratchetwheels fast on the journals atone end of the feed-rolls, suitable arms loose on said journals andprovided with paw-ls to engage the ratchetwheels, a sliding plateconnected to said box,

links uniting the pawlarms and plate, a crank arm, a rod uniting thesliding plate and crank arm, and a piniongear connecting said crank armand crankshaft, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atRacine, in the county of Racine and State of Wisconsin, in the presenceof two witnesses.
